Let's break this down. We're going to add 7701 and 2363 together.

Step 1: We'll start by adding the digits 1 & 3 in column 1 and get 4.

Step 2: We'll start by adding the digits 0 & 6 in column 2 and get 6.

Step 3: We'll start by adding the digits 7 & 3 in column 3 and get 10.
We'll write down the last digit 0 and carry the 1 to the next column.

Step 4: We'll start by adding the digits 7 & 2 in column 4 and get 10.
We'll write down the last digit 0 and carry the 1 to the next column.

So, 7701 + 2363 = 10064.
